A limited number of Azure virtual machines were provisioned without the R installation files that should be included with SQL Server. The issue applies to virtual machines provisioned in the period from 2018-01-05 to 2018-01-23. This issue might also affect on-premises installations, if you applied the CU3 update for SQL Server 2017 during the period from 2018-01-05 to 2018-01-23.

If the instance of SQL Server has been installed to a non-default location, such as outside the `Program Files` folder, the warning ACCESS_DENIED is raised when you try to run scripts that install a package. For example:

184

185

The reason is that an R function attempts to read the path, and fails if the built-in users group **SQLRUserGroup**, does not have read access. The warning that is raised does not block execution of the current R script, but the warning might recur repeatedly whenever the user runs any other R script.

If you have installed SQL Server to the default location, this error does not occur, because all Windows users have read permissions on the `Program Files` folder.

If you create a model using a decision tree or decision forest method and specify the learning rate, you might see inconsistent results when using `sp_rxpredict` or the SQL `PREDICT` function, as compared to using `rxPredict`.
